A week out, gather the physical paperwork together: the EU pet passport or health certificate, and if you filed the Tullverket customs report online, a printed or saved copy of the registration number you were issued. Keep these somewhere accessible, not buried in checked luggage.

Pick up basic tick-prevention treatment now if you haven't already, available over the counter at any Swedish pharmacy once you arrive, or bring your own from home if your pet is already on a specific product.

Check the calendar against allemansrätten's seasonal leash rule: if any part of your trip falls between 1 March and 20 August, plan your walking routes around keeping your dog leashed in nature for that whole window, and check in advance whether any national park on your route has extra trail-specific restrictions covered in the Activities section.
